Abstract (en)
[origin: WO9640477A1] A glass fiber mat for stampable sheet wherein long fibers and short fibers are not separated from each other but dispersed in each other uniformly even after molding and therefore exhibit their respective characteristics. The equipement is provided with a laminator of double belt press type which laminates a fed glass mat with a molten thermoplastic resin extruded from an extruder and a film wound off, presses the laminate thus obtained under heating to impregnate the mat with the molten thermoplastic resin and cools the resulting laminate under pressure to form a sheet, means for feeding a glass mat to the laminator, and a pair of rollers placed between the feeding means and the endless belt of the laminator and cutting part of the glass fibers of the mat into short fibers by passing the mat between them under loading. These rollers are made of steel and apply a linear load to the glass mat to thereby cut the continuous fibers and disperse the resulting short fibers in long fibers uniformly.
